B. If the fault symptom is identified by the crew observation: ENG1-oil quantity indication higher than on engine 2:
(1) Do a check for overserviced tank. Drain unwanted oil quantity.
(2) Do a check to make sure that the oil tank level confirms the oil quantity indication on the lower ECAM display unit.
(a) If the check confirms the fault:
- smell the oil for signs of fuel in it.
1 If confirmed:
_
- replace the servo fuel heater (Ref. AMM TASK 73-11-20-000-002) and (Ref. AMM TASK 73-11-20-400-002)
- replace the main oil/fuel heat exchanger (Ref. AMM TASK 79-21-20-000-002) and (Ref. AMM TASK 79-21-20-400-002).
(b) If the check does not confirm the fault:
- replace the XMTR-OIL QTY (4002EN) (Ref. AMM TASK 79-31-15-000-041) and (Ref. AMM TASK 79-31-15-400-041).
1 If the fault continues:
_
- do a check and repair the aircraft wiring from the oil quantity transmitter (4002EN) to the SDAC1 (1WV1), SDAC2 (1WV2) and EIU1 (1KS1).
(c) If the oil quantity indication is replaced by amber XX on the lower ECAM display unit:
- do a check for 28VDC at the oil quantity transmitter (4002EN).
1 If there is no 28VDC:
_
- do a check of the aircraft wiring between the circuit breaker (1EN1) and the oil quantity transmitter (4002EN) (Ref. ASM 79-36/01).
2 If there is 28VDC:
_
- do a check and repair the aircraft wiring from the oil quantity transmitter (4002EN) to the EIU1 (1KS1): pins AA/3, 4 to pins AA/8F, 8H (Ref. ASM 79-36/01).
a If the fault continues:
_
- replace the EIU-1 (1KS1) (Ref. AMM TASK 73-25-34-000-040) and (Ref. AMM TASK 73-25-34-400-040).
C. Do a minimum idle check (Ref. AMM TASK 71-00-00-710-006).
